AUXILIARY INLET DEVICE FOR INTERNAL-COMBUSTION ENGINES.

zine-lest.

To all (o /1.0m it may concern:

Be. it known, that 1, CHARLES Poi-1L, a citizen of the United States, residing at Los Angeles, county of Los Angeles, State of California, have invented a new and useful Auxiliary Inlet Device for Internal- Combustion Engines, of which the following is a specification.

In my Patent No. 1,397,780 for fuel feeding system, granted November 22nd, 1921. l: disclose a valved device attached to the intake manifold of an engine and connected by tubing to the top of the radiator and to the top of the fuel tank for inducting watery vapor and. hydrocarbon vapor into the engine. said device also having a valve controlled air inlet port to admit auxiliary air to the manifold between the carburetor and the engine.

Also in my patent for system of supplying combustible mixture to an explosive engine, No. 1.381331 issued June 14, 1921. there is disclosed a valved device connected by tubing with the upper portion of the fuel tank and with an air heating chamber mounted on the exhaust manifold for inducting hydrocarbon vapor and hot air into the manifold between the carburetor and the engine cylinders.

This present invention comprises a device devoid of suction-opened valves and it may be connected up in the manner disclosed in either of the above mentioned patents or in any other desired manner. In the drawings the invention is shown connected with the radiator and fuel tank after themanner disclosed in the above first mentioned patent. but it is to be un derstood that such showing is merely illustrative and that it is for the purpose of making clear how the invention operates.

An object of this invention. as distinguishing from the invention disclosed in the hereinbefore mentioned prior patents. is to make provision for definite adjustments to different engines and carburetors. so that the device will be of universal application.

Another object is to provide for ease of adjustment of the device in accordance with the conditions arising from using the device with different types of engines and carburetors.

Other objects and advantages will appear hereinafter.

Patented July 4:, 1922.

Application filed August 10, 1920. Serial No. 402,587.

The accompanying drawings illustrate the invention.

Figure 1 is an elevation of a conventional automobile engine, radiator and fuel tank, to ether with the invention which is shown connected up ready for operation.

Figure 2 is an enlarged elevation partly in section, on the line indicated by hi -X F 1.

Figure 3 is a front face elevation of the device looking toward the left in Fig. 2.

Figure 4: is an elevation of the invention looking at the rear face thereof.

Figure 5 is an enlarged sectional eleration on the line indicated by X X Fig. .2. the tubes being omitted.

Figure 6 is an enlarged sectional elevation on the line indicated by Xf-X, Fig. 3. I

The. engine is indicated in neral by the character 1. and is provided v. th an intake manifold 2. The engine, in this instance. is waterjacketed in the usual manner and the water jacket is connected by a pipe 3 with a radiator l. Connected with the nninifold 2 is a carburetor 5 of any desired construction. said carburetor receiving its supply of fuel through a tube 6 from a fuel tank A. l

The invention is constructed as follows: Into the intake manifold 2 is screwthreaded the nipple 7 of a chambered body 8. the chamber being indicated at 9. The chamber 9 communicates with the manifold 2 through a port or ports 10, which extend through the nipple 7.

Rotativelv mounted in the chamber 9 is a cylindrical chambered valve 11 having a pair of annular shoulders 12. 13 adapted to seat against corresponding annular shoulders l4. 15. respectively. inside of the member 8. The valve ll. is held in place bv a nut 16 screw-threaded onto a stem 17 which passes through holes 18 in the valve 1, and through a .hole '19 in the body 8, the holes 18. 19 being axially aligned. The chamber of the valve is indicated at 32.

The stem 17 is provided at the end opposite that engaged by the nut with a head 20 adapted to bear against thev outer end of the nipple 7 when the nut 16 is tightened against the outer face of the valve 11. "When it is desired to turn the valve 11 the nut 16 will be turned slightly so as to loosen it.

The peripheral wall 21 of the valve cham ber 32 is provided with ports 22 arranged,

in this instance, in two series, the ports of each series being of different diameters. The ports 22 in one series are adapted to selectively register with a port 23 extending laterally through the body 8, the outer portion of said port 23 passing through'a nipple 24 formed on the. body 8 The ports in the other series are adapted to selectively register with a port 25 extending laterally in the body 8, the outer portion of'the port 25 extending through a nipple 26 formed on the body 8.

.In the position of the valve 11 shown in F igl'5 ports 22 of like diameter are in registration with the ports 23, 25, but, if desired the valve maybe rotated to a positionin i which ports 22 of different diameters may be caused to register with the ports 23, so as to obtain a still different combination of active port areas.

. Thenipples 24:, 26 may be connected to'any suitable sources of hydrocarbon vapors and hotair, or hydrocarbon vapors and watery vapor 111 any deslred manner, the 1nvent1on not resldlng 1n the manner of connecting up the, body 8. However, for the sake of clearness in describing the invention and its operatlon, in Fig. 1 of the drawings it is shown connected with the radiator 4 and fuel tank A, the nipple 24 being connected by tubing 27 with-the radiator, and the nipple 26 being connectedbytubing 28 with the fuel tank.

Preferably the outer. face of the valve'll forms a dial 29, provided with graduations which graduations are to be aligned with thenipples 24, 26 for different makes of engines and carburetors. Thus. for a Ford car, with its regular equipment of carburetor,

. the valve 11 will be adjusted to one position,

and whenthe device is placed on a Cadillac car having. regular carburetor equipment the valve 11 will be adjusted to a different position. .Of course other adjustments may be necessary, if theowner of the car changes the type of carburetor employed therewith. I As the invention is connected in Figure 1 of the drawings, it is clear that upon operation of the engine watery vapor from the upper portion of the radiator will pass through the tube 27 into the manifold 2, and

that hydrocarbon vapor from the fuel tank manifold 2 to theremix with the combustible mixture entering the manifold from V the carburetor 5.

I claim: 1. In an auxiliary inlet device for internal combustion engines, the combination of a member containing a plurality of intake ports and having an outlet port adapted to communicate with the intake manifold of an engine, and a valvemember having two series of ports, the ports of each series being of different diameters and the ports of one series corresponding in diameter with the respective ports of the other series, and said valve member being adjustable to different positions and the ports being spaced so that when the valve member is in some positions ports of like diameter will register with the intake portsand so that when the valve member is in a different'position ports of different diameters will register with the intake ports.

2. In an auxiliary inlet device for internal combustion engines, the combination of a body having a cyl ndrical chamber thereln,

and a nipple at one end thereof, there being a port opening from the chamber and extending through the nipple, a chambered valve having a wall portion fitting the chamber of the body and having an annular shoulder fitting against the other end of the body, there being ports extending through the peripheral wall of the chamber and other ports in the peripheral wall of the valve adapted to register or not register with the last named ports according" to the positions to which the valve is turned, a stem extending from the body through its chamber, and a nut screw-threaded onto the stem to releasably secure the valve against turning.

3. In an auxiliary inletdevice for internal combustion engines, the combination of a body having a cylindrical chamber therein and a nipple at one end thereof, there being a port opening from the chamber and extending through the nipple, a chambered valve open at the end adjacent the port and having a wall portion fitting the chamber of the body, there being ports extending through the peripheral wall of the chamber and other ports in the peripheral wall of the valve adapted to register or not register with the last named ports according to the positions to which the'valve is turned, a stem extending from the body through its chamber and through the valve, and means on the stem to retain the valve in place.

Signed at Los Angeles,California, this 2d day of August 1920.
